Boost is one of the best cart upsell apps available in 2025, offering persistent cart functionality with up to 4 reward tiers, built-in upsells, and AI-powered recommendations. It's praised for its easy setup, customization options, and ability to increase average order value by 30% on average. The app works out of the box and provides excellent customer support when needed.
While Boost offers a 7-day free trial, alternatives like Aftersell Post Purchase Upsell and Qikify Checkout Customizer provide free plans with basic upsell functionality. Aftersell focuses on post-purchase offers with 1-click checkout upsells, while Qikify allows checkout page customization. However, Boost's comprehensive all-in-one approach with persistent cart, bundle builder, and multiple upsell positions makes it unique in the market.
Setting up reward tiers in Boost Cart is simple. After installing the app, navigate to the Cart settings in your Shopify admin. You can create up to 4 reward tiers combining discounts, free shipping, and gifts. For example, set 'Free Shipping at $75, 15% off at $100, 25% off at $200, Free Gift at $250'. The progress bar automatically shows customers how close they are to unlocking the next reward, encouraging them to add more items to their cart.
Boost's Bundle Builder increases average order value by allowing customers to create custom product combinations. You can set up different box sizes (2, 3, 5+ items) with a 'buy more, save more' structure. This encourages shoppers to try multiple products while feeling they're getting a good deal. The personalized experience leads to higher satisfaction and increased lifetime value as customers discover their favorite products through the bundle experience.
Yes! Boost includes Moneyboard, a comprehensive analytics dashboard that tracks exactly how much extra revenue your store generates from each feature. You can see performance breakdowns for cart upsells, bundle builder, post-purchase offers, and checkout upsells. The dashboard provides ROI visibility with time-based analysis, allowing you to monitor your store's progress and make data-driven decisions to optimize your conversion strategy.
